Use the Free Up Space Feature in File Explorer

This is the standard method to remove local copies of your files while keeping them safely stored in your OneDrive cloud.

Windows 10 and 11 include a feature called OneDrive Files On-Demand. This allows you to view all your cloud files in File Explorer without having to download them all to your local hard drive.

1
Open File Explorer

Press the Windows key + E to open File Explorer, then navigate to your OneDrive folder from the left-hand navigation pane.

2
Select Files or Folders

Locate the files or folders with a green check mark icon, which indicates they are currently taking up space on your local drive. Highlight the ones you no longer need stored locally.

3
Free up space

Right-click the selected files or folders and click 'Free up space' from the context menu. The green check mark will change to a blue cloud icon, indicating the file is now online-only.

Accessing Online-Only Files: Online-only files will automatically download again the next time you open them, provided you have an active internet connection.

Frequently Asked Questions

What does the green check mark mean on my OneDrive files?

A solid green check mark means the file is set to 'Always keep on this device' and takes up local disk space permanently. A hollow green check mark means it was downloaded temporarily and is also taking up space.

Will selecting 'Free up space' delete my files from OneDrive?

No. Using 'Free up space' only removes the local copy from your physical hard drive. Your files remain completely safe and accessible in your online OneDrive cloud storage.

How do I open an online-only file later?

Simply double-click the online-only file (which will have a blue cloud icon) in File Explorer. As long as your device is connected to the internet, Windows will download and open it automatically.

Can I automate the process of making unused files online-only?

Yes. If you use Windows 10 or 11, you can enable Storage Sense in your system settings to automatically change synced OneDrive files to online-only if they haven't been opened for a specified number of days.
